Description

Technical Field

[0001] The present invention relates to the field of construction auxiliary devices, and particularly to a curing film laying machine for cylindrical piers. Background Art

[0002] After the concrete column pier is poured, in order to prevent the moisture in the concrete from evaporating too quickly, resulting in dehydration, the cement particles that have formed a gel cannot be fully hydrated, cannot be transformed into stable crystals, and lack sufficient adhesion, causing flaky or powdery peeling on the concrete surface. In addition, when the concrete does not yet have sufficient strength, premature evaporation of moisture will also cause large shrinkage deformation and dry shrinkage cracks. Therefore, the curing in the initial stage after concrete pouring is very important, and curing should be carried out immediately after the concrete has finally set.

[0029] Example 1

[0030] As Figures 1-10 shown, the present application discloses a curing film laying machine for cylindrical piers 7. Different from the existing laying machine that drives the wrapping structure to move up and down through a cylinder or a hydraulic cylinder, so that the wrapping structure can wrap the curing film on the surface of the pier 7, the present application moves spirally along the surface of the pier 7 through the climbing system 1, so that the wrapping system 3 connected to the climbing system 1 can lay the curing film 4 on the outer surface of the pier 7 along the moving path of the device, reducing the floor area of the device and facilitating the transportation of the device.

[0031] The device includes a climbing system 1, a wrapping system 3 is connected to the climbing system 1, a moving system 5 is connected to the climbing system 1, and surrounding systems 2 are symmetrically connected to both ends of the climbing system 1. The device contacts the surface of the pier 7 through the climbing system 1, and the moving system 5 provides power for the device, enabling the device to climb spirally along the pier 7. According to different usage requirements of the device, the climbing direction can be from top to bottom or from bottom to top. In order to prevent the climbing system 1 from falling off the pier 7 during operation, the surrounding systems 2 symmetrically arranged at both ends of the climbing system 1 are used to increase the contact area of the device with the surface of the pier 7. The two surrounding systems 2 and the climbing system 1 together form a wrapping angle greater than 180 degrees to prevent the device from falling off the surface of the pier 7. During the movement of the device, the wrapping system 3 provided on the climbing system 1 is used to lay the curing film 4. A plurality of curing films 4 are placed on the wrapping system 3. After the open end of the curing film 4 is pasted on the surface of the pier 7, the device climbs to wind the curing film 4 along the moving wheel path of the device. The climbing system 1 includes an arc-shaped plate 11, the concave surface of the arc-shaped plate 11 contacts the surface of the pier 7, thereby increasing the contact surface between the arc-shaped plate 11 and the pier 7. A moving part 12 is arranged on the contact surface between the arc-shaped plate 11 and the pier 7. The moving part 12 is a sphere, and the moving part 12 is rotatably connected to the concave surface of the arc-shaped plate 11. One end of the moving part 12 fits with the surface of the pier 7. By the rotation of the moving part 12, the friction between the device and the pier 7 is reduced. When the moving system 5 drives the device to move in a specified direction, the moving part 12 can rotate in accordance with the moving direction of the device, which is smaller and more compact than a conventional universal wheel, and the operation steps required to change the rotation direction are reduced. A plurality of moving parts 12 are arranged at equal intervals on the arc-shaped plate 11. A positioning hole 13 for connecting the moving system 5 is provided at the center of the arc-shaped plate 11. A support frame 14 for connecting the wrapping system 3 is connected to the arc-shaped plate 11.The wrapping system 3 includes a positioning disk 31. The outer contour of the positioning disk 31 is a disk with positioning columns provided at the bottom end. The positioning disk 31 rotates on the top end of the support frame 14. The positioning columns are rotatably connected to the support frame 14. A motor for providing power for the rotation of the positioning disk 31 is connected to the support frame 14. The output shaft of the motor is connected to the positioning column at the bottom end of the positioning disk 31 through a coupling. A plurality of first positioning blocks 32 are arranged at equal intervals along the circumferential direction on the positioning disk 31. A limit column 33 is connected to the first positioning block 32. A second telescopic rod 34 is arranged at the front end of the first positioning block 32. A moving block 35 is connected to the moving end of the second telescopic rod 34. A second compression spring is sleeved on the second telescopic rod 34. The two ends of the second compression spring are respectively connected to the second telescopic rod 34 and the moving block 35. A scraping plate 36 is connected to the moving block 35. The second compression spring is used to push the moving block 35, so that the scraping plate 36 connected to the moving block 35 contacts the surface of the pier 7, thereby being able to extrude the curing film 4 wound on the surface of the pier 7, so that the air between the curing film 4 and the surface of the pier 7 can be discharged. A connecting frame 38 is rotatably connected to the first positioning block 32. A positioning rod 37 is arranged at the bottom of the moving block 35. The connecting frame 38 is sleeved with the positioning rod 37. The outer contour of the positioning rod 37 is rectangular. An inclined plate is arranged at one end of the top of the positioning rod 37 close to the pier 7, which is convenient for the connection between the connecting frame 38 and the positioning rod 37. The curing film 4 is sleeved on the limit column 33. One end of the opening of the curing film 4 is wrapped on the contact end of the scraping plate 36 and the pier 7. The limit column 33 is used to support the curing film 4. By inserting the curing film 4 on the limit column 33, the curing film 4 can rotate around the limit column 33 as the axis, which is convenient for winding the curing film 4. A transmission rod 15 is arranged at the top end of the support frame 14. The transmission rod 15 is rectangular. A buffer plate is arranged on the end surface of the top of the transmission rod 15 with the opposite rotation direction to the positioning disk 31. The top end of the transmission rod 15 abuts against the bottom end of the contacting connecting frame 38. A device is connected to the support frame 14 to gradually push the connecting frame 38 to rotate upward by using the buffer plate, so that the connecting frame 38 is separated from the positioning rod 37, so that the second compression spring in the compressed state pushes the moving block 35 to move, so that the scraping plate 36 connected to the moving block 35 contacts the surface of the pier 7, thereby laying the curing film 4 on the surface of the pier 7. A control module is connected to the convex surface of the arc-shaped plate 11. The output end of the control module is connected to the output end of the motor for controlling the switch of the motor.The control module observes and determines the curing film 4 sleeved on the limit post 33 opposite to the pier 7. When the curing film 4 is less than the preset value, the positioning disk 31 is driven to rotate in the counterclockwise direction, so that another first positioning block 32 connected to the positioning disk 31 moves accordingly. During the movement of the first positioning block 32, the bottom end of the connecting frame 38 connected to it contacts the top end of the transmission rod 15 and gradually pushes the connecting frame 38 to rotate upward, so that the connecting frame 38 separates from the connected positioning rod 37, and the moving block 35 moves towards the pier 7. Thus, the front end of the scraper 36 connected to the moving block 35 contacts the surface of the pier 7, and the curing film 4 wrapped by the front end of the scraper 36 contacts the surface of the pier 7, which can realize the replacement of the curing film 4 and enable the new curing film 4 to wind around the surface of the pier 7.

[0032] Embodiment 2

[0033] Based on Embodiment 1, as Figures 1-10 shown, the surrounding system 2 includes a fixing plate 21 connected to one end of the support frame 14. The fixing plate 21 is connected to the support frame 14 by bolts. According to the different models of the pier 7 to be wound, the fixing plate 21 is replaced, so that different specifications of the surrounding system 2 are connected to the support frame 14 to ensure that the two surrounding systems 2 cooperate with the climbing system 1 to form a wrapping angle greater than 180 degrees with the surface of the pier 7. A connecting rod 22 is connected to the fixing plate 21. One end of the connecting rod 22 is hinged with a steering rod 24. A sliding groove 23 is provided on the end face of the connecting rod 22 close to the steering rod 24. A slider 26 is slidably connected in the sliding groove 23. A first telescopic rod 25 is hinged on the end face of the steering rod 24 close to the connecting rod 22. The other end of the first telescopic rod 25 is hinged to the slider 26. A tension spring is sleeved on the first telescopic rod 25. The two ends of the tension spring are respectively connected to the first telescopic rod 25 and the steering rod 24. The other end of the steering rod 24 is hinged with a surrounding plate 27. A torsion spring is connected to the surrounding plate 27. Through the cooperation between the connecting rod 22, the steering rod 24 and the surrounding plate 27, one end of the device wraps the pier 7. According to the different sizes of the pier 7, the steering rod 24 will be pushed to rotate, changing the angle between the connecting rod 22 and the steering rod 24. The first telescopic rod 25 is connected between the connecting rod 22 and the steering rod 24 to limit the steering rod 24. The tension spring sleeved on the first telescopic rod 25 provides a contraction force for the steering rod 24 to move towards the connecting rod 22, so as to ensure that one end of the steering rod 24 can contact one end of the pier 7. The outer contour of the surrounding plate 27 is arc-shaped, and the concave surface of the surrounding plate 27 fits the surface of the pier 7. By connecting a torsion spring to the surrounding plate 27, a steering force is provided for the surrounding plate 27, so that the surrounding plate 27 can continuously contact the pier 7, improving the connection stability between the device and the pier 7.

[0034] Embodiment 3

[0035] Based on Embodiment 2, as Figures 1-10 shown, the mobile system 5 includes a positioning sleeve 51. The positioning sleeve 51 is arranged on the support frame 14. The positioning sleeve 51 is rotatably connected in the positioning hole 13 through a support plate 17. A driving wheel 52 is rotatably connected to the positioning sleeve 51. The driving wheel 52 is internally provided with a driving motor, and the driving motor provides power for the rotation of the driving wheel 52, so that the driving wheel 52 can rotate on the surface of the pier 7, providing power for the device to climb spirally around the pier 7. A sliding rod 53 is slidably connected to the positioning sleeve 51, and a grip 54 is arranged at the top end of the sliding rod 53. By rotating the grip 54, it is convenient for the staff to change the orientation of the driving wheel 52, thereby changing the moving track of the device to adapt to piers 7 of different sizes. A plurality of second positioning blocks 55 are arranged at equal intervals along the axial direction on the sliding rod 53. A positioning plate 16 is arranged on the support frame 14, and the positioning plate 16 is inserted into the contacted second positioning blocks 55. A first compression spring is sleeved on the sliding rod 53, and both ends of the first compression spring are connected to the second positioning block 55 and the positioning sleeve 51 respectively. When it is necessary to change the orientation of the driving wheel 52, the construction worker presses down the grip 54 to separate the second positioning block 55 connected to the sliding rod 53 from the positioning plate 16, and rotates the grip 54 to change the orientation of the driving wheel 52. After the orientation of the driving wheel 52 is determined, release the grip 54 to make the first compression spring sleeved on the sliding rod 53 push the second positioning block 55 to move, so that the corresponding second positioning block 55 is inserted into the positioning plate 16 for locking, avoiding the change of the orientation of the driving wheel 52 under the influence of external force during the operation of the device.

[0036] Embodiment 4

[0037] Based on Embodiment 3, as Figures 1-10As shown, a safety system for preventing the climbing system 1 from falling is connected to the pier 7. The climbing system 1 and the safety system are connected by a steel cable. The safety system includes a positioning frame 6 fixed at the top of the pier 7 by bolts. A steering column 61 is rotatably connected to the center of the positioning frame 6. The top of the steering column 61 is connected to a support frame 62. A tensioning wheel 63 is rotatably connected to an eccentric position of the support frame 62. The bottom of the steering column 61 is connected to a positioning wheel 64. One end of the steel cable is connected to the positioning wheel 64 and wound around the tensioning wheel 63. The other end of the steel cable is connected to the support frame 14 through a connection ring 18. A safety motor is connected to the positioning wheel 64. A measurement module is provided on the arc-shaped plate 11. The output end of the measurement module is connected to the input end of the safety motor. The safety motor is used to provide safety measures for the arc-shaped plate 11 when the arc-shaped plate 11 falls off the pier 7. When the arc-shaped plate 11 moves along the pier �, the safety motor drives the positioning wheel 64 to rotate in the moving direction of the arc-shaped plate 11 to ensure that the steel cable does not restrict the movement of the arc-shaped plate 11. When the arc-shaped plate 11 slides when falling off the pier 7, the measurement module sends a signal to control the safety motor to lock itself, so that the arc-shaped plate 11 will not continue to fall and ensure the safety of the device.
